SPECIFICATION forming part of Letters Patent No. 701,007, dated May 27, 1902. Application filed January 29, 1900. Serial No. 3,186. (No model.)

To all whom, it may concern.-

Be it known that I,J OHN B. BARTHOLOMEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented new and useful Improvements in Cultivators, of which the following is a specification.

Figure l is a side elevation of a mechanism embodying my improvements. Fig. 2 is a top View. Figs. 3 to 7 show details. Fig. 8 is a modified form of cultivator. Fig. 9 is a plan view of that in Fig. 8. Figs. 10 to 15, inclusive, show the details of the forms in Figs. 8 and 9.

In the drawings the machine represented is shown as havinga main frame, a wheel-frame, and draft devices, together with the plowframes and the parts for connecting and supporting them. The main frame can be of any suitable character. It is shown as comprising the side bars A A, together with the crossbar a and a cross-bar B. The draft devices also may be of one form or another, though I prefer to use substantially such as are shown, they consisting of a tongue 0 and means for hitching the horses thereto, as at C. The tongue, as shown, is rigidly secured to the cross-bars a and B. The wheel-frame comprises the parts 6 e 6 these'being preferably formed of a single piece of metal bent to the form of what is generally termed a crankaxle, (indicated as a whole by E.) The wheels F F are mounted upon the spindle parts 6 of this axle. The central part 6 is arranged transversely of the machine and is pivotally connected to the main frame. The arms e extend downward from the rocking or pivoted part c to the spindles e G G indicate the plows. Inasmuch as these can be of any numerous forms, it is unnecessary to describe all of the parts of either in detail. As shown, each gang or each set of shovelsis provided with and carried by a beam or main bar, which at its front end is loosely connected to the main frame. The connecting devices which I employ are constructed and arranged as follows: The above-mentioned cross-bar B is extended downward, at the sides of the machine, as shown at l) b, and the end parts are turned inward to form the spindles b b. Upon each of these spindles there is placed a pipe-box G, adapted to rock thereon. Upon the outside of each of the pipe-boxes there is placed a laterally-adjustable eyepiece I, which can be set in any desired position by means of a screw at 2'. As the pipe-box and the eyepiece are non-circular in section, the eye is prevented from rotating on the box and the eye is cast with a tubular bearing 71', which receives the vertical pivot-bolt of one of the plows or shovelgangs.

Each beam or plow-gang is provided with a spring holding and lifting mechanism constructed and arranged as follows:

J is an arm projecting from and preferably cast with the pipe-box G. To this arm is pivoted the bar K,Which extends upward through and is loosely held by a guide It, carried by the main frame. The pipe-box also has rigid with it an arm L. M is a spring which at one end is connected to this arm L and at its other end is connected to the upper end of the bar K, which latter has a hook K to receive it.

The parts of the spring mechanisms above described are more or less similar to those which have been known since the date of the patent, No. 351,684 to Avery and Berrien, dated October 26, 1886; but I have found that under some circumstances this spring mechanism can be used more advantageously if employment be made of supplemental devices, such as those shown at N N N N N is a spring; N, a crank-bar or lever-arm secured to the pipe-box. N is a connecting device between the spring and the lever, preferably a chain, and N is an adjustable connecting or supporting device for the upper end of the spring. This connecting device, as shown, consists of the parts it and n. n is a plate fastened to the machine and formed with a series of notches varying vertically in their positions, and n is a hook-rod connected to the spring N and adapted to be seated in either one of the notches n in the plate '11. The bar or lever N extends backward from the pipe-box far enough to give the desired leverage. It, together with the spring N and the supporting devices 92 and n, serves to hold the gang or plow-beam in whatever position the operator selects and insures a perfect regulation of the depth of the working. The

' the axis of the crank-axle.

operator can at any time readily adjust the parts in this respect by placing the hook-rod n in a higher or lower notch, as occasion requires. 1

As concerns the parts just described, it will be seenthat the pipe-box constitutes a vertically-rocking hinge element for the beam,

while the clevis or forkat the front end of the beam serves as a horizontally-rocking hinge element.

the beam in such way as to be inactive in relation to the latter as concerns its lateral or horizontal movement, one being active vertically at times when the other is approximately inactive.

One of the objects of the present invention is to provide amachine which can be readily converted from a walking-cultivator to a riding-cultivator, and vice versa. To accomplish this, the wheel-frame is connected to other parts, which adjust and hold it as follows:

0 is the seat. It is supported upon a frame having the bars 00, which are pivotally connccted to the main frame, as by hinging them to the part c of the crank-axle. The seat and its carrier can be turned either into'the riding position, as shown in Fig. 1, or can be turned forward, so the seat is in the position shown in Figs. 8 and 9.

-P P are cranks connected with the seatframe. They can be so connected in the way shown-that is, by extending bars 13 outward from the seat-bars and rigidly joining the cranks Pthereto, these cranks rocking around These cranks are connected by links Q with cranks R. Thelatter are mounted on the cross-bar B or otl1erwise mounted on the frame. The links Q may be shaped as required. For instance, they may be straight, as in Fig. 8 and others, or bent, as in Fig. 1, according to the relative positions of adjacent parts. links connecting these cranks Rwith the spindles b of the wheels. When the seat is turned to its rear position, the seat-frame causes the cranks P to draw backward .on the links Q, and these cause the rocking of the cranks R, which in turn push backward upon the links S and the wheel-spindles, causing the crankaxle to rock on the axis of the part at e sufficiently to carry the wheel-spindles to a line in rear of the vertical plane of the said axis. When the wheels are in this rear position, a certain amount of the weight of the machine is thrown to the front of the wheel-spindles,

and this serves to counterbalance the weight of the operator. When, on the other hand, the seat is swung to the forward position, the

movements of the parts above named are re- 'versed, and the wheels are placed in front of the axis of the part c, and as the operator is now walking the rear part of the machine is used to balance the forward part.

The seat-support bars 0 are bent from flat metal and arranged to extend to points in front of the axis of the hinge of said support and It will also be noted that both of the spring holding devices are connected to S represents l tobearagainst themain frame or againstabutl ments, as shown, situated at points in front of said axis, and the bars 13 are also formed of flat metal separately from the bars 0 and extended outwardly therefrom, these furnishing the hinging means for the seat-support and also the power-transmitter, by which the seatsupport can be utili ed to regulate the position of the ground-w eels.

In Figs. 8 to 15 there is shown a cultivator substantially similar to that above described in detail. In this case the spring M and the thrust-rod K are both in rear of the cross-bar 13, while in the construction in Figs. 1 and 2 the thrust-bar K extends upward on the front side of the cross-bar, the hook K being carried over the latter to engage with the spring M. Similarly there are minor differences as concerns the details relative to the parts which connect the seat-support O with the axle-bar e. In this case the pipe-box G has a socket cast thereon to receive the bar N. In the machine shown in Figs. 1 and 2 the main bars of the seat-support O extend under the axlebar a and have their front ends arranged to impinge upon stops on the main frame when the seat is in its lower position, whereas in the machine shown in Figs. 8 and 9 the seat is pivoted to the axle-bar by means of cast boxes or bearings, and they are stopped from descending too low by having the arms 1) arparts of the side bars A of the frame. In either machine both the springs M and N are so arranged and so connected to the plowbeam that there will be no interference from either with the free lateral movements of the beam. The spring N will be practically inactive, except when the beam is in about its working position, and the spring M will be inactive, or practically so, except when the beam is rising or descending.

What I claim is- 1. l he combination of the frame, the draft devices, the supporting-wheels, adjustable relatively to the draft devices and frame, the plow-beam, the double-acting spring connected with the plow-beam, and the supplemental spring arranged to hold the plow-beam in its normal working position substantially as set forth.
